Even though CT scan has serious negative effects, it’s certain that it has more benefits than risks. Whether CT scans are threats to people having a cancer or not, there’s one thing that is certain. Our world is constantly improving in technology. Researchers provide the best technology they can discover to help people save their lives faster. There’s no technology that is perfect.
